Hah, I was pretty sure to click on everything again but you may be right. Or it's possible that some of them don't count in the 35 important ones and I'm just completely missing one.
Still very nice idea, I really enjoyed it. It's got a mix of old flash games nostalgia with the added bonus of revisiting previous areas for new interactions (never saw that before in browser games). If you work some more on the complexity of the puzzle you're going towards Amnesia/Layers of Fear territory. I think it would be cool to have something like that easily accessible (no download required). Let me know when you get on mobile :D
